Magnetic Attraction

So, with freshly rebuilt dynohub wheel safely returned to me, and Univega waxed, following some mucky January mile munching, it was time to switch to fixed. 

Following frankenpute euphoria, you’ll imagine my dismay at a flickering and sometimes unresponsive computer display. Big fat flashing zeros are not cool.  

Let us be clear (as the present UK administration is so fond of touting). I had inserted fresh CR2032 cells, adding a slither of Vaseline to the battery contacts, nipped the sensor ties and magnet tight…Most probable causes isolated.

A seasonal Lurgy curtailed further diagnostics, but all seemed to be behaving normally. Both on the work stand and a subsequent mile long loop.

Three days later, back in the saddle, out along the lanes. Dynamo on, blinkies pulsing, erratic readouts... So, I switched the Trelock LS 906 https://www.sevendaycyclist.com/trelock-ls906-dynamo-front-light  lamp off. Consistently accurate, precise readouts resumed. Fluctuations gone.  This remained the case, over two rides and 45 miles.

I’ve never experienced these symptoms with my Univega’s Ultegra, or elderly Nexus hub dynamos. However, Strong magnetic forces, such as those experienced around power plants, and pylons are notorious points of interference. 97.6mph along a long, straight road, anyone? 

 I am also advised Shutter Precision hubs have particularly strong magnets.

Carbon fibre can also prove conductive, which is why good quality greases/assembly pastes must be used on metal components, to avert risk of galvanic corrosion/seizure. Bottom bracket threads being prime candidates. Could it be that the wonder weave, is amplifying said magnetic field, and creating these irregular signals?  

This may dictate moving sensor and magnet to chain-stay and rear wheel. Doing will exhaust computer and sensor cells a little faster. But provided I don’t exceed the 1 metre rule, everything should play nicely.

A wired unit is my last resort. Aside from defeating my “make do and reinvent narrative”, I’ll need to be more mindful when performing headset strips, and similar maintenance.  Blackburn have advised they no longer keep spares for the Atom units and, surprisingly, have deleted computers from their range.

Another rummage through the bodge box unearthed this VDO M3 WL, which appears to have a sensor fault. I’ve tried all the above techniques, but they won’t play nicely. Nor any other brands, for that matter, so I’ve emailed their UK importer for help. 

Despite constant headlines threatening a second ice-age, the thermostat has hovered around a seasonally typical 5 degrees.

No call for spikes just yet, although the wind chill prompted donning of Northwave Balaclava, once or twice.  These Oxford bright 4.0 gloves https://www.sevendaycyclist.com/oxford-1

have also come into their own and Steve’s been impressed by Proviz Reflect 360 CRS Plus Jacket https://www.sevendaycyclist.com/proviz-reflect360-crs-plus-jacket  

Chainsaw oil is continuing to do the business and some 140 miles in, is probably the closest to a bike specific, wet lubricant. I’m bargaining 500 miles from a single application. On paper, it’s looking a costlier option, compared with the bargain basement 5w/40. However, the latter attracted more scuzz. Most apparent within the cassette.

There’s been some further perch swapping, courtesy of this Pro Turnix gel saddle, which now graces my fixed gear winter/trainer. Its Selle Italia Novous boost superflow has been ported over to my tubby tourer and I’ve earmarked the BBB Echelon, elsewhere. Possibly the Goldhawk Roadax, if I can’t live with its stock/OEM model.

CAFAM Redemption & Frankenpute

Well, the CR50 arrived bang on cue but being holiday season, I zoned in and played with, the IRD CAFAM2 https://www.sevendaycyclist.com/ird-cafam-2-cantilever-brakes . 

Cantilever posts were sanded intensely, yet judiciously, using a fine grade of sand-paper. Next, a generous slither of Park PPL2 grease.

The cable and anchor bolts were both looking a little scabby too. So, new Jagwire Pro Road cable https://www.sevendaycyclist.com/jagwire-pro-road-brake-kit  and a Genetic straddle wire.

Fresh consumables instated, it was a question of painstakingly adjusting the spring and straddle wire tension, toeing pads in etc. Light and temperature dipping fast, I’d got modulation, power and feel perfect.

Serendipity was again, my friend. Ditto my elderly feline, who required his food bowl replenishing. Cable stretch isn’t an issue with better quality inner wires, so I wasn’t surprised to discover all was peachy the next morning. Fifteen miles of climbs and descents reaffirmed this.

It also proved an ideal opportunity for a saddle swap, and to rack up some miles with the chainsaw oil. 40 miles spent traversing wet, greasy backroads and the side-plates have cultivated a slightly grimy beard, However, in keeping with my fixed gear’s galvanised model “fling” has been minimal. The cassette also looks a good bit cleaner, than it did, when the chain was running 5w/40 motor oil.

Now, Frankenpute…

That corridor between Christmas and New Year is ripe for experimentation and bodge box rummaging. While doing some general housekeeping, I found four scrap computers. One with a dead head unit, one with a broken bar mount bracket and the other a defunct sensor.

I then decided to challenge myself. Build one good unit, from the three scrappers. Finding which combination would play nicely, took a while. However, with fresh CR cells and a spare magnet, this 20function, Revolution head proved compatible, with the other, cannibalised parts.

A big rubbery shim and cable ties ensured secure tenure, to my fixed’s Soma Condor bars https://www.sevendaycyclist.com/soma  

Admittedly, black would win aesthetically but white are at least, uniform. I’m unsure whether it’s the shutter precision hubs’ strong magnets. However, other wireless systems, including this Knog NERD, gave erratic, or zero readings, even with the usual remedies (i.e. fresh batteries and Vaseline on the contacts). Given this track record, I wasn’t surprised to discover these intermittent faults teasing me, on our first, misty morning test run.

Sure, its cost me in terms of time. I wouldn’t be doing these things during billing hours but being holiday season. I found the process relaxing, and end results very satisfying. In common with the CAFAM, sometimes it’s the process of really getting to grips with, and mastering something. I am also looking for a replacement sensor, for this relatively elderly (2009/10), yet extremely solid Blackburn Atom 4.0.

In case you hadn’t noticed, I have a fiercely strong bond with my machines. My working bikes. Much loved but designed to be ridden, whatever the weather. Hence why Jeff Rutland’s Goldhawk Roadax resonated so deeply with me https://www.sevendaycyclist.com/goldhawk-bicycles-purposeful-passio . In anticipation of the test bike’s arrival, I’ve dusted down my Bob Yak homage…

Aside from its hauling capacity, the mighty single wheel trailer is a means of testing a test bike’s laden handling characteristics. I am of course, referring to touring, commuting, cyclo cross derivatives, not race bikes. Laden with 20 kilos, (sometimes more) I hunt down some sweeping descents, and aim for 30mph, plus.  

The Roadax is a sportier build than, the Kinesis Tripster Ace https://www.sevendaycyclist.com/kinesis-tripster-ace  . The Kinesis is more of a cruiser, thanks to the more relaxed positioning but will do tagalong and trailer tugging duties very competently. The Roadax should be master of most trades. I’m looking forward to finding out.  

In the meantime, can’t start 2019 with a filthy fleet, or an impure kettle…

Primal Stirrings

Despite the seasonal increase in lost/stolen parcels, these Primal Dawn men’s bib knickers made it through. Formative feelings are very positive.

Bridging the gap between shorts and thermal bib tights, ¾ lengths are perfect for autumnal and early spring rides. Milder winters too. (That said; Primal cite an optimal operating temperature range, between -7 and +24 degrees) In fact, ¾ lengths my preference over bib tights, unless wind chill/air temperature really bites. Our medium fit my 1m81, 70 kilo-frame perfectly.

The bibs offer ample coverage to the vital organs, the braces, unrestricted movement. Though less common, these days (especially at this price point) the elastic in some designs can be overly firm. To the point of feeling restrictive. Several in my collection, leaving unsightly tell-tale branding, after a couple of hours riding.

Panelling and cut seem equally precise. I managed 16miles in 45 minutes during our first outing and on the fixed. Much of that fuelled by very controlled rage, induced by an inflammatory communication, from my ex-wife. Nothing particularly new there. Another example of resilience, which I touched upon in my last entry. The season of goodwill generally slumps during December, on the roads, too.

I wasn’t surprised to find myself on the receiving end of some crass overtaking. Now, simply put, if you want to kill someone without experiencing punishment, incarceration, or indeed, loss of licence-do so with a car, or larger vehicle.

The occupant of a Mercedes Sprinter began overtaking (on a bend) but then decided he might collide with an oncoming vehicle, so just swung back. I’ve had closer encounters but was fuming at this display of elephantine ignorance.

The Sprinter remained stationary, engine running for around thirty seconds, blocking my progress. A baleful “Sorry mate, are you OK?” was offered on three occasions. I remained silent and unresponsive, partly in the hope my contempt would register. Life is very short, responding would only serve to ease his awkwardness. Hopefully this experience gave him food for thought/improvement.    

On the alternative lubes front, after 480 miles that familiar, subtle metal-on-metal tinkling struck. This coincided with a well-deserved sudsy scrub, for Ursula, who was sporting a fair bit of accumulated grot around the fork legs, bottom bracket shell and chainstays.

This was dismissed with some Pro Green MX Cycle Wash https://www.sevendaycyclist.com/pro-green-mx-triple-pack . Fenwick’s foaming chain cleaner and Green Oil bicycle brush https://www.sevendaycyclist.com/green-oil-bicycle-brush  had cassette and chain gleaming, ready for chainsaw oil.  Applied via dropper bottle, this went on in a fashion, reminiscent of Weldtite TF2 extreme wet chain lubricant https://www.sevendaycyclist.com/weldtite-tf2-extreme-wet-chain-lubr  and some others adorning my shelves.

However, I was surprised by the initial clean up required. There was a fair bit of excess clinging to the side plates and a spattery patina (reminiscent of that effect employed by Kona on their late 1980s mtb frames) adorning the Univega’s chainstays. Less drizzle n’ go than bike specific blends but not markedly worse than the motor oil, in many respects.

On some levels, its to be expected, but the fixed has been running much cleaner and the lube is really clinging to the chain’s dimpled galvanised texture. Several wet rides in, the chain has almost “bedded in” and the initial gravely patter, replaced by a serene swoosh.

Talking of gravelly, (and before the so called “beast from the east” sweeps in Steve has just reviewed these GoodYear County https://www.sevendaycyclist.com/goodyear-county-premium-tyre  

Ison Distribution have been investigating my SP PD8 dynohub wheel https://www.sevendaycyclist.com/halo-rim-and-shutter-dynohub-disc-b  and confirm the hub is fine. However, the rim appeared to be pulling itself apart (albeit, very slowly). Therefore, they’re stripping the wheel and rebuilding with a new hoop.  I’ve also decided to revisit the Univega’s front stopper.

Though the IRD CAFAM 2 cantilevers https://www.sevendaycyclist.com/ird-cafam-2-cantilever-brakes  are beautifully engineered, their mechanical advantage better suits traditional levers.

My Univega’s existing Microshift are shallower reach. Great for smaller hands, but Avid Shorty 4 and M system designs are better pairings. The humble cantilever is becoming harder to come by, although still has a solid following in ‘cross circles.  Some Shimano CR50 presented themselves, so we’ll see how they fare.

Resilience & Roadax

 Resilience, the ability to keep going, regardless of what’s hurled our way, is one of those attributes that cycle, and motorcycle touring/racing nurtures. By the bucket load.

Battling an epic storm, lashing a busted rack back together, or remounting following a nasty spill. All part of the ride, develops character, coping mechanisms and self-knowledge. 

I don’t meditate in the commonly accepted sense, but as the miles and asphalt whizzes past, so ideas are explored, and solutions arrived at.

With the right kit, winter can be a very engaging, or miserable experience, depending on your chosen attire and bike prep. https://www.sevendaycyclist.com/winter-wonderland-2-destination-spr  

420 miles in, my Univega’s chain still sports a decent layer of 5w/40.Aside from a gungy beard, cultivated during the first fortnight, it’s attracted surprisingly little contaminant.

I’m still bargaining on another 100 miles, before replenishment’s called for. At which point, I will switch over to the chainsaw oil. Unless of course, something bike-specific lands on our test bench.

Gritting lorries have been spotted, these past few nights, a clear indicator that winter means business. Take this opportunity to treat painted, plated and polished surfaces to a hard paste waxing.

Pressed for time?

Car Wash n’ wax shampoos will clean and impart a waxy barrier (remember to rinse salt spattered bikes with fresh, cold water first). Pro Green MX after shine 101 can also be used on a damp, freshly washed bike. Simply spray a light film and leave to cure. No buffing, or polishing required. https://www.sevendaycyclist.com/pro-green-mx-triple-pack   

My elderly feline is also beginning to nuzzle these Schwalbe Winter but we’ll see… https://www.sevendaycyclist.com/schwalbe-winter-spiked-tyre     

With SP PD8 hub https://www.sevendaycyclist.com/halo-rim-and-shutter-dynohub-disc-b  receiving expert care, from their UK distributors, Ison Distribution www.ison-distribution.com I’ve popped the Halo SL9 https://www.sevendaycyclist.com/halo-evura-shutter-precision-sl9-dy  in its place and putting the Passport Galvanised chain though its paces.

Unsurprisingly, given its half the KMC X1’s asking price, the Passport lacks the same level of refinement. However, this is only apparent when under load. Climbing out of the saddle, with my full 70 kilos dancing on the pedals, or accelerating hard. Crucially, it feels solid, during this, or transmission braking. 350 miles, or so, before I reach any solid, tangible conclusions, though.

Staying with wet wintry stuff, Steve has been putting Silkolene Premium Cycle Lube Wet  through its paces https://www.sevendaycyclist.com/silkolene-premium-cycle-lube-wet   

Winter and working bikes are a big draw for me. Machines built to be ridden, day in, day out, rain or shine. The sort of working bikes that you love but don’t induce palpitations, when locking up in the street.

Reynolds 520 frame tubing might not hold the wow factor of 853, or similar tubesets. However, its blend of performance, price and durability lends it perfectly to the design brief.

Up front, there’s a carbon fork (with alloy steerer) continuing the lightweight, compliant theme. Although, on steel framesets, a bent derailleur hanger is easily coaxed back into line with an alignment tool, Jeff has gone for a replaceable hanger. Another sensible move, given the design brief.  

Clearances for 700x42c tyres, cyclo cross/gravel bike genre geometry, braze-ons for four-point carriers, full length guards… Hydraulic discs, capable of stopping rider (and trailer/tagalong), on the proverbial sixpence. Oh, and a decent spread of gears to ensure you can winch up hill, bomb down dale and cruise with similar ease.

I think Jeff Rutland has cracked this design brief with the Goldhawk Roadax.   

I met Jeff in Spitalfields, a London district I once knew very well. I still retain a strong attachment to the East End, and its side streets. Superficially, these have been gentrified beyond all recognition. Three minutes away and things felt reassuringly familiar. Environments where the Roadax thrives. However, the versatility of its design also bodes well, far from the maddening crowd.

In a nutshell, I can’t wait to swing a leg over its top tube, and do some serious mileage.

On your Marks, Get Set…Winter

Winter technically begins on the 21^st of December. While the weather follows the UK narrative (i.e. mild and wet), I’m prepping the fleet for the kind of apocalyptic conditions predicted by our red top, tabloid press. Talking of which, here’s our guide to winter, bike preparation https://www.sevendaycyclist.com/winter-wonderland-one

First up, I’ve replaced my fixed gear winter/trainer’s KMC Z1 inox https://www.sevendaycyclist.com/kmc-inox-chain  chain, which has served several thousand miles.

Why? Well I received this Passport Galvanised unit, which tips the scales, at a reassuringly substantial 309g. 133 less than the KMC. Weight wasn’t the motivating factor. Its also half the KMC’s asking price, so I’ll be keeping a watchful eye on longevity/durability.

I’ve used “rustless” galvanised designs to good effect, on my Univega. However, they still require regular, light lubrication. I also noticed a tendency for them to succumb to the dreaded orange taint, once the galvanised component, finally wore through. I say finally, since I racked up 2,000 wet, grotty miles from a budget 8spd model.

Nigh on dry from the packet ensures fitment was a very clear affair and proved the ideal opportunity, to start testing that chainsaw oil.

My hypothesis is that it will prove more durable, compared with the 5w/40. After 285 miles, that applied to the KMC was almost spent. However, my Univega’s electroplated Sram has cruised past 300 and at this rate, I reckon its good for another 150.

Obviously, snowy, slushy conditions may well reduce this. Its worth pointing out that the factory lubricant most chains are impregnated with, is similarly tenacious. Makes sense to run that, get your money’s worth and then use your chosen tipple.   

Workstands make maintenance and repair considerably easier, since machines are held securely, and at a convenient height.

Price dictates quality.

The needs of a home enthusiast, who may use theirs a few times each week, are different to the demands of a shop/pro mechanic. My lightweight Revolution (Edinburgh Bicycle Co-op) unit continues to serve me very well, after 10 years.

There’s some tell-tale flex, apparent when tackling high torque applications, such as bottom bracket replacement, or seized contact points. Otherwise, its solid, convenient, and very portable.

Oxford products have sent me their Torque Workshop Stand. This also retails at £99.99, employs a similar composite head but is considerably heavier.

This translates as superior rigidity. Ideal when tackling those more stubborn tasks. Less convenient for popping in the car, say for race day. Several weeks of intensive fettling will provide more tangible insight/conclusion.   

Now for the rider. Oxford also sent us these Bright Gloves 3.0. They’re a relatively slender, nimble waterproof design with a tech friendly index tip. I was slightly surprised to discover the gloves have an operating range of between +5 and 10 degrees, less than the Lusso I’ve been testing. On the other hand, its more typical of a milder, British winter. Oxford will be sending us the 4.0 too, which are theoretically windproof, too. 

Temperature is also a very personal thing.  An hour or so, at +4 hasn’t left me with chill hands but crosswinds and other factors may say different, especially on longer outings.

Some folks are more sensitive than others; or find temperature harder to regulate. Wind chill can render numbers academic. Dexterous digits are another definite plus when choosing winter gloves. I’ve had some “duvet” types, which have been blissfully comfortable, when the mercury’s slipping close to zero.

Unfortunately, a flat, mechanical, or phone call can dictate their removal, resulting in precisely the numbness, and cold they were intended to counter.

Staying with cold weather kit, Steve has also been very impressed by these Stolen Goat Deep winter Bib Tights https://www.sevendaycyclist.com/stolen-goat-deep-winter-bib-tights

So, thoughts turn to Christmas. Any of these make decent main/stocking filler presents but if you are struggling to buy for those riders in your life. The sort who appear to have everything, then how about the re-hook tool. Hardly essential but its designed to reclaim a dropped chain, reputedly in three seconds. No mess, no fuss. www.rehook.bike/guide

Lighting, Lubes & Log Cabins

So, I’ve reached our conclusions regarding the Ugoe 2000 headlight https://www.sevendaycyclist.com/ugoe-2000   and The Oxford Bright Stop rear LED light https://www.sevendaycyclist.com/oxford-bright-stop-rear-led-light I’ve turned my focus to mile munching with the Schwalbe Marathon Mondial https://www.facebook.com/Sevendaycyclistmagazine/videos/1367504860051913/  which are performing convincingly, both on and off road. https://www.facebook.com/Sevendaycyclistmagazine/videos/324364064784396/c

No, they’re not a trail tyre, in the cross country mtb sense. Rather they’re go-anywhere, all-terrain rubber. Sure, they’re not going to carve through the gloop like an aggressive knobbly, or glide over asphalt with the same speed as a slick.

However, rolling resistance is considerably lower than their weight and 26x2.0inch profiles would suggest. Off road, they’ll take unmade tracks, bridle path and less intense forest trails, in their stride. The stuff that really turned me on, to mountain biking as a teenager. Also explains Gravel’s appeal (much the same principle, just tackled on bikes with more cyclo cross in their DNA).

Lightweight, rugged machines that could go anywhere and perform with similar finesse. Slower across asphalt than a road or touring rig but the ability to vanish at speed along a dirt road. Feeling the ear to ear grin grow and leaving the world behind.

Powerfully enticing now, much less a bored teen, stifled by school’s rigid conformity. I wasn’t disinterested in education, just the context and curriculum. Thankfully, there were a few suitably disruptive students, for teachers to actively “zoo-keep”.

This left me to read the latest Specialized or Cannondale test, sans introspection, let alone chastisement.  My sincerest thanks go to Jane Wright (as she was, then) who rose from her seat and burst into the Communards’ “Don’t leave me this way”. Surreal, in the Dennis Potter sense. Perfectly timed, mid-afternoon, during double French, with Miss Diaper...

Back to 2018…

As things turn wetter, thoughts turn to waterproof kit and we’ve also been putting some wallet friendly panniers, https://www.sevendaycyclist.com/oxford  mudguards https://www.sevendaycyclist.com/oxford-full-length-mudguard-kit  and tyres https://www.sevendaycyclist.com/vee-tire-co-easy-street-tyre  through their paces. Aimed at commuters, all three seem to offer a decent amount of bang, for modest buck.

  

The motor oil challenge continues and much as I expected. The 5w/40 remains very stoical but is collecting moderate amounts of gunk, which are being purged on a weekly basis before it becomes a drivetrain gobbling, grinding paste.  Stoicism aside, shifts are very slick and silent, I latterly dribbled a tiny drop into every link.

There’s no one formula, for every occasion, in my experience, hence I like to alternate between lubricants, depending on the season. Self-cleaning wax types are particularly appealing. Low friction, lower maintenance (save for more frequent reapplication).

Home brewed variants are also extremely cheap to make (once you’ve got the consistency right). However, some commentators forget that the time and materials invested in this, have a cost (not to mention, mess) implication, which pushes their real “start-up” cost considerably higher (although I fully appreciate this can be recouped quite quickly over time).

Similarly, if you are unsure of correct brewing procedure, buying stock products is much cheaper than an explosion. The sort, resulting in an open plan terrace, and strained neighbourly relations.   

One of the major advantages shared by motor oil, chainsaw oil and more traditional wet lubes, is the ability to drizzle on, wipe and scoot off. Perfect during late autumn and winter, where daylight is at a premium.

Speaking of forest fun, Sharon booked us a Forest Holidays break, in Nottingham last week. https://www.forestholidays.co.uk/?channel=ppc&gclid=Cj0KCQiAoo7gBRDuARIsANeJKUZ7A2ySyU__cEKkSfGO4ECVjym1pua6fPB-flh5RolooJh1ngRO6IYaAt14EALw_wcB&gclsrc=aw.ds

Despite some poor light, and inclement conditions, I managed a fair bit of mooching and captured a bit of trail action, for good measure.

En route up, I dropped my Shutter Precision PD8 dynohub wheel, with John Moss. Unfortunately, John says the hub is poorly, rendering spoke tensioning academic. Thankfully, Ison distribution www.ison-distribution.com have come to my rescue and will sort, under warrantee…
